`FileNotFoundException` in `deploy` stage when log file is missing

[mabartos]

Describe the bug

The deploy job fails with FileNotFoundException when a pr-jobs-* file exists in logs/ but the corresponding pr-log-* file is missing.

This happens when the log download failed and was cleaned up by the fix in #59, but LogFailedParser.parseTest still tries to open the log file unconditionally.

java.io.FileNotFoundException: logs/pr-log-29024314313 (No such file or directory)
    at java.io.FileInputStream.open0 (Native Method)
